Question

Add the equations.

5x - y = - 1
+-5x + 3y = 25

Answer 1

Answer:

C. 2y = 24

Step-by-step explanation:

The sum of x-terms is 5x + (-5x) = x(5 -5) = 0.

The sum of y-terms is -y +3y = y(-1+3) = 2y.

The sum of the constant terms is -1 +25 = 24.

The result is ...

... 2y = 24

Answer 2

C

Add the like terms from both equations on both sides

(5x - 5x ) + (- y + 3y ) = - 1 + 25

0 + 2y = 24

2y = 24 → C
